Be it known that I, JOHN W. MASURY, of New York, in the county of NewYork and State of New York, have invented certain new and usefulImprovements in Cans and I do hereby declare the following to be a full,clear., and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it,reference being had to the accompanying drawings, which form part ofthis specification.

My invention relates to an improved can or package for paints or othersubstances.

'lhe object of this invention is to securea softmetal top to a can orpackage in such a manner that the can or package shall be perfectlyair-tight, and preserve the contents of the package from contact withthe atmosphere, and consequent deterioration from such oxposure.

The can is of such construction that it is of sufficient strength at thepoint where the softmetal top is attached thereto to withstand anyordinary pressure experienced during the transportation of the' same,and thus preserve the reliability of the joints.

Another object of the invention is to form the joint between thesoft-metal top and the can in such a manner that the top may be easilysevered at its outer edge by a horizontal cut of a knife, whichoperation results in forming a pail of an improved form of construction,and adapted for any of the ordinary uses of a pail or bucket.

My invention consists in the combination, with a can or package providedwith an upper wired edge, of a soft-metal top, soldered to the outersurface of the can, whereby the wire serves to impart suicient strengthto the can to render it specially adapted for safe transportation, andalso serves to constitute a groove about the upper edge of the can orpackage, within which the solder is placed to secure the edge of thesoft-metal top to the outer surface of the can, and thus eiectuallypreventing the solder from running within the can, or upon the upperedge of the same, which would prevent the ready severance of the topfrom the body of the receptacle.

In the accompanying drawings, Figure l represents a side elevation of myimproved of the same. Fig. 3 is a vertical section with the top removed.

A designates the body of the can or package, which may be round or oflany desired form, and made of any desired material.

A bail, B, may be secured to bail-ears C, soldered to the outer surfaceof the can, if desired, and thus enable the package to be transformedinto a pail or bucket, having the same iinish and strength of ordinarypails.

Thenpper edge of the can or package is turned outwardly over a wire, D,thereby constituting a smooth rounded upper edge, E, and a groove ordepression, F, just below the upper edge of the package.

G represents the soft-metal top, the outer edge a being turneddownwardly over the wired edge, and an air-tight joint formed by placingthe solder in the groove F, thus firmly uniting the soft-metal top tothe outer surface of the can or package.

This method of securing the parts renders it impossible for any solderto run inside of the can, or lodge and harden on the rounded upper edgeof the same, which would seriously interfere with the easy severance ofthe top from the body of the package.

When it is desired to remove the top G, a knife-blade is insertedthrough the outer edge ofthe soft-metal top, and the handle depresseduntil the knife is brought to a horizontal position. As the upperrounded edge is perfectly smooth, it constitutes an easy bearing for theblade as it is forced around the edge of the package, and allows the topto be removed without the necessity of inserting the pointl of the knifeinto the contents of the package. After the top has been removed thebody of the package constitutes a pail of improved construction, thesame havingasmooth upper edge, which is strengthened by a wire, thusrendering it adapted for any of the uses for which such vessels areemployed.

The additional strength imparted to the package by means of the upperwired edge is a matter of great importance in connection with air-tightpackages, for the reason that when the wire is dispensed with the upperportion of the package is capable of sustaining but little pressure,owing to the very light transporting solids or liquids of any character.

Having fully described my invention, what I claim as new, and desire tosecure by Let-l ters Patent, isy ,f

Au air-tight package or can, consisting, es sentially, in thecombination, with a can or package having an upper wired edge, of asoft-metal top soldered to the outer surface of the can, substantiallyas and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this27th day of February, 1877.

JOHN W. MASURY.
